Plans: A/B test displaying features list vs. description in Plan v2

[danhauk]

This is a second iteration on #2924 with a more focused hypothesis. Testing by adding a third variation to remove a few features from the list.

Hypothesis

eCommerce and Google Analytics are key drivers toward Business plan signups.

Variations

description	list	andMore

Testing

With description text

• Visit http://calypso.localhost:3000/start in a new browsing session.
• Run localStorage.setItem( 'ABTests', '{"plansFeatureList_20160215":"description"}' ); in your browser.
• Proceed through signup to the plans step.
• Assert that you see a sentence as the description for each plan.
• Assert that you see the same description on /plans/:site after signing up.

With full features list

• Visit http://calypso.localhost:3000/start in a new browsing session.
• Run localStorage.setItem( 'ABTests', '{"plansFeatureList_20160215":"list"}' ); in your browser.
• Proceed through signup to the plans step.
• Assert that you see a list of features (like in the screenshot above) for each plan.
• Assert that you see the same list of features on /plans/:site after signing up.

With truncated features list

• Visit http://calypso.localhost:3000/start in a new browsing session.
• Run localStorage.setItem( 'ABTests', '{"plansFeatureList_20160215":"andMore"}' ); in your browser.
• Proceed through signup to the plans step.
• Assert that you see a truncated list of features with "And more" link (like in the screenshot above) for Business plan.
• Assert that you see the same list of features on /plans/:site after signing up.

Added the "And more" link to the plan comparison and updated the a/b test start date.

👍 Product review - works as expected

[drewblaisdell]

Super minor, but we're trying to avoid ES6 syntax (like const or object destructuring) in files that haven't been fully rewritten in ES6 (there is another erroneous instance of this on line 51). This should be:

var site = this.props.site,
  siteSuffix = site ? site.slug : '';

Fixed!
